The tax applies to capital gains made since January 1. Banks have until June 1 before having to collect the tax.
“Historical” capital gains will be exempt. This means that the capital gains realized on financial assets acquired before January 1, 2026 are calculated by taking as the acquisition price the value of these assets on December 31, 2025.
The tax will apply to personal income tax or legal entity tax, but not to corporate tax which already has a capital gains tax regime.
An “exit tax” regime also established
In order to prevent this tax on capital gains from being circumvented by a change of residence of the taxpayer, an “exit tax” regime is also established.
At cruising speed, it should theoretically bring in 500 million euros per year.
This tax was one of the conditions issued by Vooruit for entering the center-right Arizona coalition. It was the subject of very long negotiations and caused strong tensions between the Flemish socialists and the MR.
The Arizona majority, the PS and the PTB voted in favor of the measure. Anders, DéFI and the far-right Vlaams Belang party voted against. Ecolo-Groen abstained.
The vote took place at 3:00 a.m., after a general discussion marked by a five-hour speech by Vincent Van Quckenborne (Anders). The Flemish liberals tabled no less than 33 amendments, without success. The amendments tabled by the other opposition groups were also rejected.
